LETTER FROM THE PRESIDENT OF IPA

My name is Peter Vinci and I am the president of IPA. I would like to thank you for

your interest in IPA’s product line and share my commitment to you, our products

and our policies. In today’s world, we have all experienced the lack of service and

consideration demonstrated by many companies after you buy their products. They

say whatever they can to make the sale, and then it’s like pulling teeth to get any

service response out of them. I know this myself ﬁ rsthand and because of this, I

want to be sure that your experience with IPA meets your expectations and that IPA

never disappoints you with our service or customer response.

To prove my commitment to you, if for any reason, you are not happy with one of

our products – or more importantly, with the response from our customer service

department, or any member of the IPA team – I invite you to contact me directly via

my email, [email protected] or call me at 888-786-7899. Your satisfaction is more

important to me than the sale itself. We will not be in business for long if we don’t

make you completely happy with our products and service. I want IPA to be different

and be known for its quality and service.

With that said, please take a look at our product line. You will see innovative ﬁ rst time

products that were created to help you do your job faster and better than before.

I would also like to invite you to critique our products. If you can think of a better way

to make them or changes that will make them work better, please contact me directly

and I will be sure to look into it. If you have an innovation and would like some

feedback, give me a call.

From all of us at IPA, we thank you for taking the time to review our product line and

wish you and your family the very best of everything.

BATTERY GASES, TESTER PREPARATION

AND TESTER/CHARGER LOCATION

RISK OF EXPLOSION

• Gases produced by a battery are highly explosive.

• Wear safety goggles and protective clothing, both

users and bystanders.

• Use in an area having at least four air changes per hour.

• Read, understand and follow all instructions for charger, battery, vehicle and any

equipment used near battery and charger.

• Do not smoke, strike a match, place metal tools on battery or cause a spark in

the vicinity of the battery. When removing battery cables, remove the ground

cable ﬁ rst.

• Clean terminals before charging battery. During cleaning, keep corrosive particles

from eyes, nose and mouth. Use baking soda and water to neutralize acid and

help eliminate airborne corrosion.

• Never allow clamps on charger cables to touch each other.

• Do not expose tester or charger to rain, snow, or wet conditions.

• Do not allow battery gases or acid to contact MUTT

cabinet. Do not place

PART 5: PRETESTING CHECKLIST

The pretesting checklist should always be completed prior to using the MUTT

UNIT PLACEMENT

• Place the tester on a ﬂ at, level surface.

• Chock trailer wheels to avoid rolling before testing brakes.

MAINTAIN CONNECTORS

Dielectric grease should be used on all connections to avoid corrosion. If a bad

connection exists at the terminal junction, you may get an erroneous reading and

the MUTT

will not work properly.

• Make sure you have a solid connection in the socket.

• Be certain the 7 pins in each plug are clean and spread to the proper size.

• Always check the MUTT

connector pins at the side of the MUTT

for proper

expansion. Over time, the pins may bend in slightly resulting in a poor connection

between the connector and the cable ends. A ﬂ at head screwdriver can be used

to expand the pins until a tight connection is made.

CABLE TESTING PROCEDURE

The MUTT

has a special cable feature to test 7-way round pin cables for continuity.

The cable testing feature can be used to test a tractor’s cable, or the supplied MUTT

cable. All cables should be tested prior to MUTT

operation.

• Insert each end of the cable into both side connectors on the MUTT

. Be sure to

push the cable ends in ﬁ rmly until they reach the bottom of the connector.

• Turn main power switch to a desired power supply.

• Once the power is selected, the green lights around the control knob will blink

and disappear one at a time until only the Ground Integrity Indicator remains solid

green. Once the initial check has been performed, poor cable conditions will be

shown by a blinking light for the problem circuit.

• If the cable has an open circuit or continuity problem, the corresponding circuit will

ﬂ ash repeatedly.

• Further testing can be performed by selecting each circuit individually via the

control knob or remote. When an open circuit is detected, the LED for the circuit

will ﬂ ash and an audible alert will be heard.

3-Button Remote Control

PART 9: ABS BLINK CODE DIAGNOSTICS

The MUTT

can be used to access ABS Blink Codes on trailers equipped with

ABS systems. Trailers equipped with ABS feature an ABS Control Unit (ECU) which

detects any electrical fault in the trailer ABS. Most trailers with ABS will also have a

dedicated ABS lamp on the driver side. Each fault has a code. When a fault occurs,

the ECU stores the code for that fault in its memory. This fault code will be displayed

on the trailer ABS lamp when the proper access sequence is engaged.

ACCESSING ABS BLINK/FAULT CODES

The MUTT

provides a quick method to trigger ABS blink codes without a tractor

present. Depending on the system, you will need to selectively power the Auxiliary

and/or Brake Light Circuit in the correct order. Instructions on how to access several

of the most common ABS systems can be found below.

Once the correct manufacturer’s speciﬁ c sequence is performed, you then must as-

sess the trailer ABS lamp. The number of blinks displayed on the trailer ABS lamp will

correspond to a speciﬁ c ABS fault. As each manufacturer uses different access meth-

ods and each blink code has different meanings, the remainder of the ABS section will

be broken down by the brand of ABS system installed on the trailer you wish to test.

Note: ABS Manufacturer Access Protocols/Blink Codes are subject to change.

Please consult speciﬁ c ABS manufacturer manuals for more detailed information and

any discrepancies in their literature shall supersede the following directions.

8.5 EMERGENCY AIR EXHAUST

To apply the parking brake at any time during testing, simply turn the Emergency

Side Air Ball Valve to the EXHAUST position.

PART 7: ELECTRICAL/LIGHTING TESTING

Complete the pretesting checklist prior to all testing procedures.

The MUTT

is microprocessor controlled and features a special diagnostic ﬁ rmware,

designed to seamlessly integrate with your preferred methods of testing. The MUTT

will power the selected electrical circuits and instantly alert you to any signs of a faulty

condition. To properly utilize the diagnostic features, a complete scan of the

trailer’s electrical system should be performed at the front of the trailer using the

MUTT

prior to a walk-around inspection. If any wiring faults are present, the MUTT

will blink or sound, alerting you to the issue. Only a one-time, walk-around/visual

inspection is needed to conﬁ rm that each individual light bulb is properly illuminating.

NOTE: Some advanced functions may not be listed on the face panel, so it’s

important to read the manual in its entirety to ensure that you are getting the full use

of this diagnostic system.

7.1 SELECTING A CIRCUIT

Circuits can be selected for testing manually, via remote control or by initiating Auto

Cycle Mode.

OPERATING WITH MANUAL CONTROL

8.3 LEAK DOWN TESTING

You must always test the Emergency Side before testing the Service Side. Trying to

test the Service Side ﬁ rst will result in erroneous readings.

EMERGENCY SIDE LEAK DOWN TESTING

1. After setting the desired working pressure, set the Emergency Side Air Ball Valve to

the CLOSED position. This will begin the leak down test.

2. Observe the needle on the air gauge and note any PSI drop after pressure stabilizes.

3. Look for air loss according to your local speciﬁ cations by noting consistent air

drop over time. If air pressure continues to drop at an unacceptable rate, you can

turn your air supply back on by setting the Emergency Side Air Ball Valve to OPEN

and attempt to ﬁ nd the source of the leak in the air system.

SERVICE SIDE LEAK DOWN TESTING

1. Set the Emergency Side and Service Side Air Ball Valves to the OPEN position.

Set the Service Side Brake Control Switch to the PRESSURIZE position. (This ﬁ lls

the Service Side air lines.)

2. Once the Service Side is fully charged, set the Service Side Air Ball Valve to the CLOSED

position.

3. Observe the needle on the air gauge and note any PSI drop after pressure stabilizes.

4. Look for air loss according to your local speciﬁ cations by noting consistent air

drop over time. If air pressure continues to drop at an unacceptable rate, you can

turn your air supply back on by setting the Service Side Air Ball Valve to OPEN

and attempt to ﬁ nd the source of the leak in the air system.

Set Emergency Side Air Ball Valve to CLOSED

Set Service Side Air Ball Valve to CLOSED

7.2 GROUND INTEGRITY TEST

Each time the MUTT

is powered on, it automatically runs a Ground Integrity Test. A good

ground connection must be established for the MUTT

to operate a trailer’s electrical system.

1. Immediately after power up, the green lights around the control knob will illuminate.

2. A solid/healthy ground connection is indicated by a steadily illuminated Ground

Integrity Indicator.

3. Bad/poor ground or bad cable condition is indicated by all of the LED’s blinking

simultaneously. See ESTABLISHING A CHASSIS GROUND below.

4. When one or more green circuit LEDs blink while the Ground Integrity Indicator

is steadily illuminated indicates that a solid ground has been established, but an

open circuit has been detected. Refer to OPEN CIRCUIT on pg. 18.

CHASSIS AND PIN GROUNDS

A poor ground warning may be an indication that the connected trailer is only wired

for chassis ground. There are two ground types. 1) Pin Ground: The ground wire

from each light assembly is wired through the main harness up into the trailer plug.

2) Chassis Ground: The ground wire from each light assembly is grounded directly to

the trailer chassis. Ground with the truck is established at the king pin.

ESTABLISHING A CHASSIS GROUND

1. To simulate the king pin on a chassis ground

connection and bypass the ground integrity fault,

plug the supplied 10 ft. chassis ground cable into

the MUTT

’s Chassis Ground Outlet.

2. Using the alligator clip, attach the other end of the

chassis ground cable to the chassis of the trailer.

3. Be sure that you are attaching to a clean, dry metal for an effective ground.

GOOD GROUND BAD/POOR GROUND

DO NOT

Assume that a Bad

Ground Warning is a

Result of a Faulty Trailer.

Check Cable Connection.

Put the Chassis Ground Cable into the Outlet

7.3 FAULT INDICATION

OPEN CIRCUIT

The MUTT

senses no load which is often the symptom of a disconnected wire, cut

wire, poor pin connection or bad return ground. The MUTT

can detect open circuits

in two ways.

1. During Ground Integrity Test: An individual circuit will blink and no audible alerts

will be present.

2. During circuit selection: The selected circuit’s LED will blink, while simultaneously the

Open Circuit Indicator will ﬂ ash. The MUTT

will also provide an audible alert (beep).

Example: The MUTT

detects an open circuit in the Clearance Light Circuit. The

Clearance LED will blink, the Open Circuit Indicator will ﬂ ash and the MUTT

will beep.

NOTE: Open Circuit Indicator will only illuminate during circuit selection.

CROSSED CIRCUITS

The MUTT

indicates that two or more circuits are back feeding or crossed. This

can be a symptom of two wires in the same harness wearing through their insulated

coating and connecting.

1. When a crossed circuit is identiﬁ ed, the selected circuit LED will illuminate steadily

and the circuit it is crossed with will ﬂ ash. The MUTT

will also provide an audible

alert (beep).

Example: The MUTT

detects that the Clearance and Tail/Tag are crossed while the

Clearance Circuit is selected. The Clearance LED will illuminate, the Tail/Tag LED will

ﬂ ash and the MUTT

will beep.

Example: Open Circuit in Clearance Light

Example: Crossed Circuit in Clearance and Tail/Tag Lights

8.2 SETTING DESIRED WORKING PRESSURE

1. Turn the MUTT

on, by selecting Battery or External power with the Power Source

Switch.

2. Set Emergency Side Air Ball Valve to the OPEN position.

3. Turn Air Regulator Knob clockwise or counterclockwise until needle on the

Emergency Side Air Gauge points to the desired operating pressure (Most shops

prefer 80-100 PSI during testing).

Set Emergency Side Air Ball Valve to OPEN, Turn Regulator to Desired PSI

PART 8: AIR BRAKE TESTING

Complete the pretesting checklist prior to all testing procedures.

8.1 TESTING SETUP

1. Push the Power Source Switch to the OFF position.

2. Set both Emergency and Service Side Air Ball Valves to the CLOSED position.

3. Attach gladhand hoses from the MUTT

directly to your trailer’s air system, securing

the red hose to the Emergency Side and the blue hose to the Service Side.

4. Connect your shop air to the Shop Air Inlet on the left hand side of the tester.

5. Listen for any air leaks where the shop air connects to the tester, to avoid

erroneous results.

Set Emergency and Service Valves to CLOSED

Push Power Source Switch to OFF

TO SERIOUS INJURY AND POSSIBLY DEATH.

Connect the Shop Air to the Shop Air Inlet

NOTE: In some cases, a crossed circuit may be a normal function of advanced

diagnostic testing, such as with certain ABS systems.

SHORT/OVERLOADED CIRCUIT

Short circuits or overloads can occur when a positive, hot wire touches ground.

They can also occur due to faulty lights or connectors.

1. If a short or overloaded circuit is suspected, the MUTT

will instantly stop

powering the circuit.

2. The Overload Warning Indicator will then ﬂ ash, along with the selected circuit’s

LED. The ammeter needle will also max out and return to 0.

3. The MUTT

will now automatically enter Pulsar Mode. During Pulsar Mode, the

MUTT

will attempt to reapply power to the faulty circuit every 3 seconds for an

indeﬁ nite period of time. After power is applied, if a short is still present, steps 1-3

will automatically repeat.

Example: The MUTT

detects a short in the Clearance Light Circuit. The Clearance

LED and Overload Warning Indicator will ﬂ ash and a warning beep will sound. The

MUTT

will now enter Pulsar Mode.

NOTE: Pulsar Mode can be a useful troubleshooting tool for ﬁ nding dead and

intermittent shorts.

Example: Short Circuit in the Clearance Light

7.4 ACTIVATING HAZARD LIGHTS:

The four-way ﬂ ashers on the vehicle can be activated manually or with the remote

control.

Manually

1. To activate, set the Hazard Switch to the ON position.

2. To deactivate, set the Hazard Switch to the OFF position.

Remote Control

1. To activate, press and hold the DOWN ARROW button for 5 seconds.

Set the Hazard Switch to the ON Position

Set the Hazard Switch to the OFF Position

Press and Hold DOWN ARROW to Activate

7.5 ALL CIRCUITS ON (OVERRIDE) MODE:

All Circuits On Mode will engage all electrical circuits at the same time. While short

circuit sensing is operational in this mode, if a short circuit is found, the MUTT

will

not be able to identify which circuit is the cause of the short. Open and crossed

circuits sensing is not operational in this mode.

On trailers using incandescent bulbs, All Circuits On Mode will typically result in an

overload because the amperage draw will exceed the maximum of 20 amps.

All Circuits On Mode can be accessed manually or by remote control.

MANUALLY

1. To activate, press and hold control knob for 10 seconds. Listen for beep, then release.

2. To cancel, press or turn the control knob.

NOTE: Does not work when ABS or Brake Light Circuits are selected.
